Why it matters: Viruses affecting rice, a staple food for more than half of the world population, pose ...

Russian scientists have discovered how the brain makes purchasing decisions. Using electroencephalography (EEG) and magnetoencephalography (MEG), researchers found that the brain responds almost instantly when a product's price deviates from expectations. This response engages brain regions involved in evaluating rewards and learning from past decisions. Thus, perceiving a product's value is not merely a conscious choice but also a function of automatic cognitive mechanisms. The results have been published in Frontiers in Human Neuroscience. Every day, people are faced with prices of food, technology, and services. Sometimes, a product seems overpriced, ...

As aging bodies decline, the brain loses the ability to cleanse itself of waste, a scenario that scientists think could be contributing to neurodegenerative conditions such as Alzheimer’s disease and Parkinson’s disease, among others. Now, researchers at Washington University School of Medicine in St. Louis report they have found a way around that problem by targeting the network of vessels that drain waste from the brain. Rejuvenating those vessels, they have shown, improves memory in old mice. The study, published online March 21 in the journal Cell, lays the groundwork to develop therapies for age-related cognitive decline that overcome ...

A new study on indoor extreme heat connects these two burdens to reveal how the co-occurrence of escalating energy bills and dangerously hot homes in Miami-Dade County exacerbates health and well-being risks for vulnerable households across months of the year. “Our findings help us understand which types of households are struggling with high indoor heat and high energy bills in a place like Miami, which is hot for many months of the year,” said Lynée Turek-Hankins, the lead author of the study that was conducted during her doctoral studies at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science and the Abess Center for Ecosystem ...

A study from Hiroshima University found that when people were told to imagine their virtual bodies in pain, their brains resisted the illusion of ownership. Their findings could provide insights into why some people may struggle with feeling connected to their own bodies, particularly in contexts involving depersonalization or negative physical states. The sense of body ownership—the feeling that our body belongs to us—is crucial in distinguishing ourselves from objects and responding to threats. Researchers study it using techniques like the rubber hand illusion (RHI) and full-body illusion (FBI), in which an individual is somehow ...

At the center of most large galaxies, including our own Milky Way, sits a supermassive black hole. Interstellar gas periodically falls into the orbit of these bottomless pits, switching the black hole into active galactic nucleus (AGN)-mode, blasting high-energy radiation across the galaxy. It's not an environment you'd expect a plant or animal to thrive in. But in a surprising new study in the Astrophysical Journal, researchers at Dartmouth and the University of Exeter show that AGN radiation can have a paradoxically nurturing effect on life. Rather ...

Diisocyanates are used in the preparation of all polyurethanes, ranging from the foams used in shoe soles to the thermoplastics used in cell phone cases. Aromatic diisocyanates, which give polyurethane foams their structure, are commonly prepared on the megaton scale in highly secure facilities due to the use of phosgene, a highly reactive and toxic chemical reagent. Michael Burkart’s lab at UC San Diego recently reported the preparation of fully bio-based aromatic diisocyanates from a simple monosaccharide, D-galactose. This new route avoids the use of transition metals, gaseous reagents or any high-pressure/temperature reactions. As an application, the team demonstrates ...

Almost half of patients diagnosed with depression classify as being ‘treatment-resistant’ as new research suggests that many don’t respond to multiple antidepressant options.   The new study, published in the British Journal of Psychiatry was led by academics from the University of Birmingham and Birmingham and Solihull Mental Health NHS Foundation Trust. The study found that 48% of patients whose electronic healthcare records reported a diagnosis of depression had tried at least two antidepressants, and 37% had tried four or more different options.    Treatment-resistant depression (TRD) is ...

A drug-resistant type of bacteria that has adapted to health care settings evolved in the past several years to weaponize an antimicrobial genetic tool, eliminating its cousins and replacing them as the dominate strain. University of Pittsburgh School of Medicine scientists made the discovery when combing through local hospital data – and then confirmed that it was a global phenomenon. The finding, published today in Nature Microbiology, may be the impetus for new approaches in developing therapeutics against some of the world’s deadliest bacteria. It also validates a new use for a system developed at Pitt and UPMC that couples genomic sequencing ...

Quantum computers have the potential to solve complex problems that would be impossible for the most powerful classical supercomputer to crack.  Just like a classical computer has separate, yet interconnected, components that must work together, such as a memory chip and a CPU on a motherboard, a quantum computer will need to communicate quantum information between multiple processors. Current architectures used to interconnect superconducting quantum processors are “point-to-point” in connectivity, meaning they require a series of transfers between network nodes, with compounding error rates.  On the way ...

Applying their technology, they lowered temperatures of miniature greenhouses by 25 degrees Celsius and increased crop yields of Chinese cabbage by nearly 200%. The study can be read in Nexus.   The nanoplastic consists of polyethylene, the most widely produced plastic in the world, infused with nanoparticles consisting of the molecule cesium tungsten oxide. These nanoparticles absorb ...

New research shows that some great hammerhead sharks are homebodies. Scientists studying great hammerheads around Andros in the Bahamas shark sanctuary have found that while some individuals migrate, others prefer to stay at home — potentially because their environment provides them with everything they need. This information could help protect the critically endangered species.  “The global population of great hammerheads is thought to have reduced by more than 80% over the last three generations, and genomic ...

Bubble baths might be soothing soaks, but bubble showers could be the next thing in keeping the skin clean. An Osaka Metropolitan University-led medical research team found that ultrafine bubble showers might help prevent atopic dermatitis. Graduate School of Medicine student Ayaki Matsumoto and Associate Professor Hisayoshi Imanishi led the study into using ultrafine bubbles, often used to clean medical equipment, on mice with atopic dermatitis. The scientists found that in mice with atopic dermatitis due to external factors, inflammation was markedly suppressed when the affected skin ...

Southern elephant seals are the “canary in the coal mine” for the Southern Ocean, offering insight into how the ecosystem may react to future climate change and human impact, new research shows. Joint senior author Associate Professor Nic Rawlence, Director of the Otago Palaeogenetics Laboratory, says while elephant seals now only inhabit the subantarctic islands and South America, Aotearoa beaches used to be “heaving” with the colossal animals. “At the time of human arrival in New Zealand, you would be hard pressed to find room on the beaches, with fur seals on the rocky headlands, prehistoric sealions and elephant seals ...

Great recipes require the perfect combination of ingredients — biotechnology recipes are no exception. Researchers from Osaka Metropolitan University have discovered the ideal genetic “recipe” to turn yeast into a tiny yet powerful eco-friendly factory that converts methanol into D-lactic acid, a key compound used in biodegradable plastics and pharmaceuticals. This approach could help reduce reliance on petroleum-based processes and contribute to more sustainable chemical production. Lactic acid is widely used in food, cosmetics, pharmaceuticals and bioplastics. It exists in two forms: L-lactic acid ...
